I used a variety of methods to generate it, from making noise that is slightly pink mostly white noise with a bit of lag 1 correlation to noise that had a long-term autocorrelation structure that was similar to the “Union” reconstruction, mixed with just a bit of white noise.

So we published an article focusing on the statistical anomalies associated with 9/11 in the journal Foundation of Physics Letters.32 One of those anomalies was that the GCP random data showed an extremely unlikely and persistent temporal structure called an autocorrelation, with odds against chance of a million to 1.
